HARRY M. GOULD, 0F PORTLAND, MAINE.

WIND OW-SCREEN.

Application filed February 14, 1916.

To all whom it may concern:

Be it known that I, HARRY M. GOULD, a citizen of the United States, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in WVindow- Screens, of which the following is a specification.

My invention relates to the construction of screen frames for windows and the object of the invention is to make a frame that will. be insect-tight, simple in construction and which may be easily and quickly taken out and put in.

The invention consists in the combination of features hereinafter described and claimed.

My invention may be best understood by reference to the accompanying drawing in which- Figure 1 is a front elevation of my screen frame shown in position in a window.

Fig. :2 is a section on the line of Fig. 1.

Fig. 3 is a section on the line g g of Fig. 1.

Fig. 4 is a section on the line as of Fig. 1.

Referring to the drawing, similar reference characters indicate similar parts.

In the drawing 1, 1 indicate the side casings of the window and 2 is the upper sash. 3 represents my screen frame which is a rectangular frame having upper and lower bars and side bars 3.

The frame fits between channeled guide strips 4 secured to the side of the casing on each side of the window opening for the purpose of holding and guiding the frame and allowing it to slide vertically.

The guide strips i are made with a front flange 4' and a rear-flange 4 formed somewhat wider than the front flange 4P. The

frame fits between the flanges 4 and is rab beted out on the rear side to receive the flange 4*. There is thus formed a double overlapping joint which allows for limited variations in the width of the casing and always remains fly-tight.

The screen frame is guided and held in place by a pair of pins on each side'which enter the grooves of the channeled guide strips.

The pins 3* aresecured to the sides of the frame at the top and as here shown they Specification of Letters Patent.

are formed of angular bolts driven into the upper end of the side rail and allowed to project into the guiding groove. The up per surface of the frame is recessed to receive the horizontal portion of the pin so that the upper surface of the frame is smooth.

The lower portion of the frame is guided by two pins 3 one on each side, here shown as driven into the edge of the frame and extending into the guiding groove.

To enable the frame to be taken out and put into position I form in the front flange l" on each side a notch or opening 4. This notch is located somewhat above the pin 3 when the latter is at its lower position.

It will be seen that by raising the frame until the pins 3 come opposite the notches 4 and pressing it outward the lower end of the screen is freed from the guides and the upper end may be easily freed by slightly inclining or twisting it in a lateral direction. The frame may be inserted in a similar manner.

For the purpose of holding the screen in a raised position, I secure a spring 6 in the upper part of the guide strip where it will engage the upper pin 3* when the frame is lifted and hold it up by frictional contact.

The guide strips are substantially the same width as the thickness of the casing strip which is almost universally inches and it is therefore easy for anybody to put in place, simply requiring to be cut off the proper length and nailed up.

A screen frame constructed according to my invention makes an insect-tight joint; it is easily put in and taken out and it may be cheaply made.

To prevent the screen from being raised from the outside I provide a catch or button 7 on the under side of the upper rail which may be turned back so that it projects immediately beneath the lower rail of the upper sash. If any attempt is made to raise the screen, the button 7 impinges on the upper sash.

I claim:

In a window screen the combination of a screen frame having rabbeted side bars, a channeled guide strip having front and rear flanges of unequal width secured to each side of the casing and a pair of guide pins at each lateral edge of said frame projecting into the channels of the guide strips, one pin of each pair being at the upper end of the frame and a notch or opening being formed in the narrow flange of each of the guide strips above the lower pin to allow the lower pin to enter and leave the channel, the Wider flange of the guide strip fitting Withinthe rabbet of the screen frame. 10

In testimony whereof I have aflixed my signature.
